You've hit on the crux of my questions/concerns about disklabels in
general. NetBSD's done a lot of cool cross-platform support, and
emmulation. So why not support multiple disklabels? I'd love to be
able to bring home a DOS zip and throw it in the mac, and read it.
While we're gaining the ability to write disklabels, why not gain the
ability to write MacOS disklabels? True, we couldn't write a driver
to the disk (well, not a new driver; we could copy one from another
drive), and I'm not sure about bootblocks, but we certainly should
be able to write macos partition tables. It'd be tricky if we don't load
the whole table into the disklabel, but we could come up with something.
And we could possably start a migration to NetBSD support of disklabel
abstraction.

Well, there's all that NetBSD/i386 code for dealing with floppies. :-)
My read is that /sys/msdosfs will work on both big and little endian
machines. Also, it supports Win95 filenames, so it supports long
filenames NOW. :-)
Take care,
